Abstract

A wireless communication link is established between a mobile station and a landline station, independently of the landline and wireless telecommunications networks. The mobile station, while engaged in a call via a wireless telecommunications network, may wirelessly transmit a bridging signal to a transceiver, in order to include the landline station in the call independently of the landline telecommunications network. While the landline station is engaged in a call via the landline telecommunications network, the transceiver may wirelessly transmit a bridging signal to the mobile station, in order to include the mobile station in the call independently of the wireless telecommunications network.

Claims

1. A cordless base unit for facilitating wireless communication between a mobile station and a landline station, said mobile station being able to send and receive calls via a wireless telecommunications network, said landline station being able to send and receive calls via a landline telecommunications network, said cordless base unit comprising:

an antenna;

a wireless transmitter communicatively coupled to said antenna;

a wireless receiver communicatively coupled to said antenna;

a telephone line interface communicatively coupled to said landline telecommunications network;

a multiplexer, for selectively interconnecting said wireless transmitter, said wireless receiver, and said telephone line interface;

a controller, for controlling said multiplexer; and

a user interface, coupled to said controller, wherein said cordless base unit provides a first communication pathway for communicatively coupling said landline station to said landline telecommunications network, said cordless base unit provides a second communication pathway for communicatively coupling said mobile station with said landline station, via a wireless communication link, independently of said landline telecommunications network, and said cordless base unit wirelessly transmits a bridging signal to said mobile station independently of said wireless telecommunications network, in response to a predetermined instruction from a source selected from the group consisting of said user interface and said landline station.

2. The cordless base unit of claim 1, wherein said cordless base unit uses a first wireless channel for communicating with said mobile station and a second wireless channel for communicating with said landline station.

3. The cordless base unit of claim 1, wherein said cordless base unit communicates with said mobile station over an air interface and communicates with said landline station over a wired connection.

4. The cordless base unit of claim 1, wherein said landline station is a cordless handset.

5. The cordless base unit of claim 1, wherein said landline station is integrated with said cordless base unit.
